showed up to look at a small chiller used to cool a laser. Maintenance guy said it wouldn't start so he called the electricians to take a look. Said they found a bad switch so they JUMPED IT OUT He said it ran but still wouldn't cool.
I put my gauges on and read 0 psi. Pressurized and evaporator reservoir overflowed with bubbles.
To make a long story short, I replaced the coil and cannot get rid of the water. I've been purging and pulling a vacuum for going on three days now. (I stop in between jobs to change pump oil and purge). My pump oil continues to be milky white every time. I can get vacuum down to 936 and will hold for an hour before purging again.
Is there anything I can do to hurry this along?
Does my vacuum reading sound right? (It won't raise much, making me think its not boiling off)
Can I throw some heat on the receiver and comp?
Thanks in advance. Will be back at it tomorrow, and hope to see some improvement.
